To all whom it nmy concern:

Be it known that I, OTTO NOLL, 01' Berlin, in the Kingdom of Prussia andGerman Empire, have invented a new and useful Steam- Motor, of which thefollowing is a specifica tion, reference being had therein to theaccompanying drawings, no patents being obtained by me anywhere for thisinvention save in Germany, No. 41,817, July 3, 1886; in Belgium, No.73,628, June 26, 1886; in Denmark, No. 857, November 16, 1886; inFrance, No. 177,630, June 26, 1886; in Great Britain, No. 9,117, July13, 1886; in Spain, No. 9,285, July let, 1886; in Italy, No. 20,157,June 30, 1886, and N0. 22,482/276, October 20, 1887, and in Norway, No.190, July 21, 1886.

My invention relates to steam-motors.

In the accompanying design, Figure 1 illustrates a front view of themotor. Fig. 2 is a section through Fig. 1 on the line X Y. Fig. 3 showsthe left side view of the motor. Fig. l is a section through Fig. 1, onthe line U Z, and illustrates the arrangement of the spiralshaped bentcoiled pipe F and the position of the nozzle E. Fig. 5' shows the rightside view of the motor. Fig. 6 represents the cocentric and thevalve-rod. Figs. 7 to 9 show the nozzle E. Fig. 10 is a longitudinalsection through the cylinder of the motor. Fig. 11 is a horizontalsection through the cylinder on the section-line o w. Fig. 12 shows asection on the line m a of Fig. 10. Figs. 13 and 11 represent theair-chamber L, with the back-stroke valve (1'. r

A designates a force-pump for supplying water to the engine. It isprovided with the back-stroke valve (1', contained in the airchamber L.This force-pump is worked by means of an eccentric from the fly-wheelshaft of the motor. It sucks up a quantity of water by means of thesuction-piece S, and forces it, according to the position of theregulatorcoek G, into the pipe B. From the latter the water passesthrough an adjustable nozzle, E, into the serpentine pipe F. Thepassageopening of the regulator-cock corresponds with the dimensions ofthe pump, so that when the regulatoncock C is shut the superfluous waterruns off through the back-stroke valve (1 and pipe b.

The back-stroke valve (1 in the air-chainber L is illustrated in Figs.13 and 14 on a larger scale. In these figures a indicates thesuction-valve; b, the delivery-valve; c, the seat of back-stroke valve,and cl the valve 5 5 itself. The latter is connected with the valve rod70 and the piston e, and moves with the piston e in the box 71, in whichthe piston e closes air-tight. The spiral spring 9' is inclosed in thespace between thepiston e and the upper screws, i, of the box and alwayspresses the back-stroke valve (1 down 011 its seat.

The air-space f of the air-chamber is connected by r, n, and q with thepump-space m, or, rather, with the pipe B. 1 6

The nozzle E is illustrated in detail in Figs.

7 to 9. It consists in the pipe E, the conical point or end of which iscut crosswise and overlapped by a casing, h. Pipe E and casing 72. areprovided with corresponding threads. By screwing the casing it onto thepipe E the hole cut in the conical end. 1 of the latter is narrowed bymeans of the cone 5. By this means the injection can be made as fine asmay be desirable. The purpose of 75 this fine injection is to insure theimmediate conversion of the water thus injected into steam within saidcoiled pipe F. This steam is superheated more and more as it approachesthe inlet to the cylinder and enters the latter as dry steam. The threadmade in the back end of the nozzle E allows of its being screwed ontothe support D. The support I) is connected by means of a flange with theserpentine pipe F, which is exposed to the fire direct. The pipe G isscrewed onto the coiled pipe F, and the steam is conducted through itinto the slide-valve box II and into the steam-cylinder.

The steam cylinder is placed above the furo nace, as is shown in Figs.10 to 12. In order to heat the cylinder it is enveloped in a mantle orjacket, which, by means of suitable plates arrailged each above theother, is made to form a spiral ascending channel, P P P The fire-gasespass through this channel, play round the cylinder, and communicate toit the heat they contain, and finally escape through pipe T into thechimney. The slide X is regulated by means of valve-rod O',having a yokeformed on one end, and an eccentric, O, turning within said yoke. Thelatter is represented in Fig. 6. The escape of steam is regulated by thevalve 4;, which is operated on by the regulator.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In a steam-motor, the spiral pipe F and the pump for supplying waterthereto, in combination with a furnace below said coil, and a cylinderabove said coil, into which the steam from the latter is discharged towork the engine or motor, substantially as set forth.

2. In a steam-motor, the spiral pipe F and the pump for supplying waterthereto, in combination with a furnace below said spiral pipe, acylinder supplied with steam by said coil, and a jacket surrounding saidcylinder and communicating with said furnace, the said jacket beingprovided with a-spiral passage through which the products of combustionpass in contact with said cylinder, for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

OTTO NOLL.
